Product Description

Seedless, Sweet, and Healthy Home-Grown Fruit

Why Ruby Red Grapefruit Trees?

The Ruby Red is America's favorite grapefruit. If you enjoy the flavor and health benefits of grapefruit but dread the tedious work of cutting it up and removing the seeds, then you'll love this grapefruit tree. The fruit is seedless, easy to peel, prepare and enjoy...especially since you can now harvest right from home.

Plus, it grows when many other varieties are dormant. You'll get an abundance of sweet grapefruits during the winter months. And the Ruby Red Tree is amazingly fruitful, rewarding you with a lifetime of plump, seedless citrus. When grown as a potted patio plant, it will thrive anywhere in the country. Simply bring it indoors during the cold months, and make sure you put it near a sunny window.

Why is Better

This fast grower is easy to own, with no pest or disease problems. So, you'll start your day with a healthy dose of home-grown vitamin C, potassium, and fiber for breakfast, baking or snacking right from the branches.

And the best part is that our Ruby Red Grapefruit Trees are groomed and nurtured at our nursery, so when they're delivered to you...they can produce fruit the very first year, hassle-free.

Order your Ruby Red Grapefruit now to get the delicious, easy-growing benefits for yourself!

Pollination Info

Ruby Red Grapefruit Tree Pollination

Ruby Red Grapefruit Trees are self-fertile. You will get fruit with only one plant. However, adding an additional Ruby Red Grapefruit Tree will drastically increase the size of your crop.

Success the first year!

I buy the largest size available, to minimize time to fruiting (usually). I bought this product from FGT. It was thriving by December 2018 and burst into blooms, followed by tiny fruit, the died suddenly. Since it had been thriving, I figured it had been my fault it died. Actually, the root stock survived and sent up vigorous shoots, but from below the graft. FGT quickly replaced the tree, with one a little smaller but maybe more vigorous. It too soon bloomed, and had a few fruit. One by one, they fell off, in the wind or otherwise, except one that was resting on four little twigs off the trunk. It persevered through summer outdoors, then this fall and winter in our sun porch. On February 8, more than a year after it started, the fruit felt rather soft, even though it had not gotten very pink, so I harvested it. It is bigger than store-bought red grapefruit available now, and very juicy and tasty. It's on the right, in the comparison of uncut fruit, then cut in the other picture. This tree bloomed well again, but is holding only one fruit, already the size of mature kumquat.

Surprising Ruby Red Grapefruit

I received one tree extra tall and in great shape, and potted it immediately. Indoors in Zone 5B, it bloomed profusely in December, then suddenly dropped all leaves and dried brown. FGT quickly sent me a replacement, which was not as tall ... but also bloomed in January. It dropped all the small fruit, over time, except one supported by a couple of short branches beneath it. That one fruit has been very entertaining ... for a full year now ... and is starting to get some orange tint to the skin, finally. Meanwhile, it has flowered again and is still holding a couple fruit the size of a pingpong ball, plus several new additional flowers right now, mid January. Probably our very short outdoor growing season makes the fruit take so long to ripen. I have another grapefruit also bearing several new fruit. I pollinated them with an ultrasonic toothbrush, but do not know how necessary that was.

Planting & Care

1. Planting: For your Ruby Red, choose a location with well-drained soil and plenty of sunlight - about 6 to 8 hours of sunlight per day.

When you're ready to plant, select a container that's about twice the width of the shipped container and one with drainage holes. From there, fill your pot halfway with soil, place your tree, and then backfill the rest with soil, leaving about one or two inches at the top. Finally, water your plant to settle the roots.

2. Watering: Be sure to water your tree regularly for its first year once each week and more frequently during the hot season and periods of extended drought.

After the first year, the tree’s roots will become a bit more established and you can reduce watering to once every two weeks.

A good way to indicate when you need to water is by using your index finger. Stick it into the pot and feel around for moisture - if there is still some present in the soil, hold off on watering. If it feels like it is drying out on the top couple inches, water just enough until you see it escaping the drainage holes and stop.

3. Fertilizing: Container-grown Ruby Red Trees will require a well-balanced fertilizer formula specialized for growing citrus, such as the one included in our Citrus Care Kit. This formula already contains all of the micronutrients that the tree will need. Feed the trees regularly, but be sure to follow the directions on the fertilizer’s packaging.

The typical time frame for container-grown citrus is to start in February and provide fertilizer once every 4 to 6 weeks until September.

4. Pruning: Remove suckers as they appear by pinching them off of the tree or using a sterilized pair of cutters to remove them. You can easily sterilize your tool(s) by wiping them with a household rubbing alcohol. Prune off any dead or damaged branches in the early spring after the threat of frosts has passed.

5. Pollination: Our Ruby Red Grapefruit Trees are self-fertile, but you can pollinate your indoor trees by hand using a small, dry, fine-tipped paintbrush. Swirl the brush around the center of each bloom and collect the pollen on the brush. Go to the next bloom and repeat the process until every bloom has been treated, and repeat the process daily. Don’t wash the paintbrush until after the blooms have been pollinated. The blooms will fall and the fruit will begin to form.
